Abstract
A Faraday rotator of multilayer film type is provided which can achieve excellent optical characteristics with a reduced number of layers. In the Faraday rotator, a metal reflection film, a periodic dielectric multilayer film made of silicon dioxide SiOand tantalum pentoxide TaO, a magneto-optical thin film, and another periodic dielectric multilayer film made of tantalum pentoxide TaOand silicon dioxide SiOis formed sequentially. Light incident on a polarizer goes therethrough, is reflected at the metal reflection film while traveling trough the periodic dielectric multilayer films, and goes through an analyzer to exit out.
